While the public has not yet seen the report, court filings from the special counsel’s team provide some clues to the major players likely to be named in it.

That includes some of President Donald Trump’s top advisers and members of his campaign, a rogue’s gallery of Russian hackers and spies and various people who played bit parts in the drama.

Below is a closer look at some of the names you may hear in the coming days and weeks.

The Key Players

Paul Manafort, Trump’s campaign chairman

A longtime Republican consultant, Manafort later went into working overseas and lobbying for foreign political figures in the U.S. before serving as Trump’s campaign chairman. During the campaign, he joined Trump’s son, Donald Jr., and son-in-law, Jared Kushner, in a meeting in Trump Tower with a Kremlin-connected lawyer who promised dirt on Hillary Clinton. He also shared valuable campaign polling data with a former business associate, Konstantin Kilimnik, who the FBI believes has ties to Russian intelligence. In 2018, Manafort was convicted of hiding income he earned representing a pro-Russia political party in Ukraine and sentenced to seven and a half years in prison for that and other charges.

Rick Gates, Manafort’s deputy

Gates, Manafort’s right hand man at his lobbying business, played a similar role in the Trump campaign and went on to work on the inauguration. He was indicted with Manafort in October 2017 and later struck a deal to cooperate with the special counsel’s office.

Konstantin Kilimnik, Manafort’s Russian employee

A Russian political consultant, Kilimnik worked for Manafort in his lobbying firm, where he was sometimes described as “Manafort’s Manafort.” Along with sharing the polling data, he and Manafort also discussed a Ukrainian peace plan, according to a court filing. Mueller’s office charged Kilimnik with attempting witness tampering, but no trial has been set.

Roger Stone, Trump’s longtime confidant

A longtime Republican operative and Trump confidant, Stone was charged for lying to Congress about his communications with WikiLeaks, which released Democratic and Clinton campaign emails stolen by the Russians, and for witness tampering. He has pleaded not guilty and his trial is set to begin in November.

Michael Flynn, Trump’s national security advisor

Flynn, a retired Army lieutenant general and former director of the Defense Intelligence Agency, advised Trump on national security issues during the campaign, worked on the transition and served as national security advisor in the White House. He resigned in February 2017 after misleading Vice President Mike Pence about conversations he had with Russian Ambassador Sergey Kislyak during the presidential transition. FBI Director James Comey testified before Congress that Trump asked him to end an investigation into Flynn. In December of 2017, Flynn pleaded guilty to lying to investigators and began cooperating with Mueller’s team.

Michael Cohen, Trump’s personal attorney

Cohen, Trump’s former longtime personal lawyer and self-described fixer, pleaded guilty to lying to Congress about his efforts to secure a Trump Tower deal in Moscow during the 2016 campaign. In a separate investigation, he was sentenced to three years in prison for making hush money payments during the campaign. He made a host of explosive claims in testimony to Congress in February, including that Trump often lied about the value of his business holdings, that he knew Clinton’s emails would be leaked ahead of time and that he spoke with Cohen about hush money payments to a porn star.

Trump’s Family

Donald Trump Jr., Trump’s oldest son

Trump’s oldest son is running the family businesses — along with his younger brother Eric — while Trump is in the White House. Trump Jr. was a key player behind the infamous Trump Tower meeting with a Kremlin-linked lawyer in June of 2016. He also issued a misleading statement to the New York Times about the meeting which turned out to have been personally dictated by the president while returning from a trip to Germany on Air Force One. Trump Jr. also later revealed that he had communicated privately with WikiLeaks during the campaign. In addition, Cohen testified that he told the eldest Trump son about his work to develop the Trump Tower in Moscow.

Ivanka Trump, Trump’s daughter

Trump’s oldest daughter, who now holds a post in his Administration, was also briefed on the Moscow tower development, according to Cohen’s testimony. During the campaign, she was also contacted by the wife of a Russian athlete who wanted to help develop a separate Trump property in Moscow, according to a report in BuzzFeed.

Jared Kushner, Ivanka’s husband

Ivanka’s husband, Kushner served on the campaign and now works in the White House. He had several Russian contacts during and after the campaign. Most notably, Kushner was present at the 2016 Trump Tower meeting with Trump Jr. and Manafort. He was also sent emails about efforts to set up back-channel discussions with Russians and about Trump Jr.’s contacts with WikiLeaks — both of which he failed to provide to Senate investigators.

The Russians

Sergey Kislyak, the ambassador

The former Russian ambassador to the U.S., Kislyak had several notable meetings with Trump associates. Flynn, the national security advisor, was fired after it came out that he had not disclosed meetings with Kislyak. Former Attorney General Jeff Sessions recused himself from overseeing the Russia investigation after it came out that he had not disclosed meetings with Kislyak in his Senate confirmation hearings. And Kislyak and Foreign Minister Sergei Lavrov met with Trump in the Oval Office less than a day after Trump fired Comey. He returned to Russia in the summer of 2017.

Aras Agalarov, the real estate tycoon

A Russian real estate tycoon who partnered with Trump to host the Miss Universe pageant in Moscow in 2013. He kicked off the 2016 Trump Tower meeting after learning that Russia wanted to give the Trump campaign dirt on Clinton.

Emin Agalarov, his son

The son of the developer and a Russian pop star, the younger Agalarov helped set up the Trump Tower meeting.

Natalia Veselnitskaya, the lawyer

A Kremlin-connected lawyer, Veselnitskaya was at the Trump Tower meeting and was the person Trump Jr. was told could have damaging information about Clinton.
